Check Digit Verification of cas no

The CAS Registry Mumber 171909-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,9,0 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 171909-67:
(8*1)+(7*7)+(6*1)+(5*9)+(4*0)+(3*9)+(2*6)+(1*7)=154
154 % 10 = 4
So 171909-67-4 is a valid CAS Registry Number.

Reactions of 5,6,11,12-tetradehydrodibenzo[a,e]cyclooctene with 1,2-C6H4(SiMe2)2Pt(PPh 3)2 and Pt(CH2=CH2) (PPh3)2. X-ray structure determination of resulting double silylated compounds and platinum-alkyne complexes

, p. 1 - 8 (1997)

The platinum complex of 5,6,11,12-tetradehydrodibenzo[a,e]cyclooctene (1), [(Ph3P)2Pt]2[1], was synthesized quantitatively by the reaction of 1 with Pt(CH2=CH2)(PPh3)2. The reaction of 1 with 1,2-C6H4(SiMe2)2Pt(PPh 3)2 gave 5,5,10,10,15,15,20,20-octamethyl-5,10,15,20-tetrahydro-5,10,15,20- tetrasiladibenzo[b,n]tetraphenylene ([C6H4(SiMe2)2]2(C 16H8)) and [(Ph3P)2Pt] [C6H4(SiMe2)2-C16H 8] (C6H4(SiMe2)2C16H 8=5,5,16,16-tetramethyl-5,16-dihydro-10,11-didehydro-5,16- disiladibenzo[a,e]naphtho[c]cyclooctene) as well as [(Ph3P)2Pt]2[1]. The central eight-membered ring of [C6H4(SiMe2)2]2(C 16H8) has a typical tub-shaped structure, while that of [(Ph3P)2Pt]2[1] is much less folded. The structure of [(Ph3P)2Pt][C6H4(SiMe 2)2C16H8] lies between those of [C6H4(SiMe2)2]2(C 16H8) and [(Ph3P)2Pt]2[1]. Crystal data: [(Ph3P)2Pt]2[1]·2toluene, C88H68P4Pt2·2C 7H8, monoclinic, P21/n, a=16.369(2), b=30.104(6), c=17.120(3) A?, β=102.69(1)°, V=8230(2) A?3, Ζ=4.
